ANIMAL-EXTERIVIINATOR.

SPECIFICATION forming part of Letters Patent No. 642,080, dated January 30, 1900. Application filed May 15, 1899. Serial No. 716,912. (No model.)

To @ZZ whom, t may concern:

Beit known that I, FRANKLIN BURNAM, a citizen of the United States, residing at Fortuna, in the county of Humboldt and State of California, have invented certain new and useful Improvements in Animal-Exterminators, and I do declare the following` to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the iigures of reference marked thereon, which form a part ot this specification.

This invention relates to animal-exterminators; and the object of the same is to inject powder or other material of a poisonous or disagreeable character into ground-holes or tree-orices to reach the runways or nests of pestiferous animals-such, for instance, as gophers-for the purpose of killing the same or causing a migration from cert-ain localities or tracts, and thereby protecting vegetation generallyfrom the destructive in roads ofsuch animals.

The invention consists of the details of construction and arrangement of the several parts which will be more fullyhereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective View of the improved externiinator. Fig. 2 is a transverse section ot' the improved device.

Similar reference characters are employed to indicate corresponding parts in both views.

The numeral 1 designates a cylindrical barrel or body having a conical-shaped reduced end or nozzle 2, and attached to the said barrel or body is a stationary substantially U- shaped handle 3, which is disposed at a convenient angle for holding the entire device steady while in use or in arranging it in position for operation. On the barrel or body 1 an expelling-cylinder -l is slidingly mounted and closely iitted thereto. This expellingcylinder is shorter than the barrel or body 1 and has a closed head 5 with a central aperture G, as shown by Fig. 2, over whicha dexible valve 7 has movement, and is attached at its free end to a valve-rod 8, movably mounted in a central enlarged top cross portion 9 of a guard 10, attached to the said expelling-cylinder. The valve 7 is fixed at one end to a part of the head 5, and the valve-rod S is secured to the inner end ot' said valve by means ot'` a nut 11 and an upper washer or disk 12. To the upper end of the valve-rod 8 a pushing-handle or cross-arm 13 is secured, and 10- cated above the central enlarged portion 9 and below said handle or arm a second pulling grip or arm 14 is also secured on the said valve-rod. These devices are primarily arranged far enough apart to fully open the valve 7 by drawing up on the valve-rod 8 through the grip or arm 14 and to cause a full closure of said valve by pressure exerted on the handle or arm 13 and reverse to the pulling action on said grip or arm 14.

It is intended that the exterminatorbe loaded or charged with a powder or other palpable material of a nature deleterious to the life of small animals or at least of such obnoxious character as to cause the animals to leave their abode. In putting the powder or other material in the device the cylinder 4 is withdrawn and the barrel or body 1 filled from the enlarged end., The cylinder 4 is again re placed in position on the barrel or body 1, and in use the reduced end 2 is inserted in a groundhole or orifice in a tree or at any other point, and to expel the powder or other material the said cylinder 4 is first drawn rearward, and at the same time the grip orarm 4 has a pulling pressure exerted thereon to open the valve 7. This opening of the valve will allow the air to iiow in behind the powder or other mate'- rial in the barrel or body 1, the said cylinder between the head 5 and the enlarged end of said barrel or body 1 then becoming an air chamber, and when the cylinder e is pushed forward the air is compressed against the rear of the load or charge of powder in the barrel or body, and an expelling pressure is thereby set up, which will drive the powder or other material out from the nozzle and spread it with considerable force in and about the coniines of the hole or orifice in which the said nozzle has been inserted. 3y successive operations of this character the powder or other material in the exterminatorcan be effectively spread, and by slightly changing the form of the nozzle without departing from the inven* tion the improved device might also be readily employed for destroying insects.

ICO

It is preferred that the parts of the device be constructed of metal, and to accommodate various uses the proportions and dimensions, as Well as the minor details of construction, might also be changed Without departing from the spirit of the invention or sacrificing any lof the advantages thereof.

arms on opposite sides of the guard and attached to the said valve-rod.

2. In an exterminator, the combination of a barrel or body having a distributing end, and an expelling-cylinder slidingly mounted on said barrel or body and provided with a flexible valve adapted to be manually operated in reverse directions, during the movement of the said expelling-cylinder, a guard, and a rod attached to the valve and movable through the guard.

In testimony whereof I aEtiX my signature in presence of two Witnesses.
